Question

Timmy used to practice the violin for 60 minutes everyday. Now, he practices 135% as many minutes as he used to. How many minutes does he currently practice everyday?​

Answer 1

81

Explanation:

create a proportion:

135/100 = n/60

next, cross multiply:

135 x 60 = 100 x n

multiply 135 and 60:

8100 = 100n

divide bith sides by 100:

8100/100 = 100n/100

n = 81

So, Timmy now practices 81 minutes every day.

hope this helps :)

Answer 2

81

Explanation:

You need to work out 35% and add it to 100% to make 135%

To do that you work out 10% and multiply it by 3 to give you 30%. After that you need to work out 5% and add it to the 30%. You can work out 5 %by dividing the answer you get for 10%

100%=60 minutes

10%=6

30%=18

5%=3

35%=21

60+21=81 minutes
